A system for reversibly converting stadiums into multifunctional infrastructure by removing the pitch and storing it in a pit (6), the pitch having a set of trays (1) having a total length equal to the pitch in a longitudinal direction of the pit, which are moveable, self-supporting and have layers of soil, irrigation and turf; a set of transport trolleys (2) for lifting and moving each tray (1) from its position on the pitch to the pit (6); a set of retractable trellises (5) that can be unfolded on the pit (6), for the entry of each tray (1) from above the pit; an elevator system (8) inside the pit (6) to move each tray to its final position, in storage, or on the pitch; and a storage system (7) for storing each tray in a fixed and stable position.

The invention concerns a movement space for carrying out physical activities, comprising a raised floor (3) having a support structure (33) bearing on the ground (2) of the movement space. The support structure supports a horizontal platform (30) comprising a plurality of openings and comprises support elements (36) for supporting detachable covers (4) in order to cover these openings. These covers are configured to cover these openings (32) in such a way as to form a substantially uninterrupted raised surface (50) on which an individual can walk and carry out physical activities. The support structure (33), the platform (30) and each opening (32) are dimensioned so as to form a housing (38), delimited vertically by the ground (2) and the platform (30), in which a trampoline (60) can be housed, the elastic surface (61) of which can be accessed through the opening (31).

A stadium including a first level with a pitch divided into a plurality of self-supporting units, a second level under the first level which houses the plurality of self-supporting units, both levels being arranged in communication through a pit, horizontal movement means of each self-supporting unit, and vertical movement means of each self-supporting unit in the pit including a first platform which can be moved in the pit between an initial position aligned with the first level, closing the pit, and an end position, and a second platform which can be moved in the pit between an initial position aligned with the first platform when said first platform is located in the end position and an end position, with the second platform aligned with the second level.
